'Rear Window' Ethics: Remembering and Restoring a Hitchcock Classic

If this is what I think it is then I saw it and found it interesting. It has lots of great anecdotes and gives great insight into life on a Hitchcock set. Even more interesting is the "restoring" part. It's amazing to me how some of the most revered movies of all time need restoration in the first place, and how little it could take back then for a masterpiece to essentially be lost forever. Of course, today, with digital storage and the internet, this is much less of an issue.
